专利号:US-7749300-B2 优先权日:2008-06-05 标题 :Photochemical synthesis of bimetallic core-shell nanoparticles 发明人:CHRETIEN MICHELLE N; WU YILIANG; CHOPRA NAVEEN 权利人:XEROX CORP 摘要:A method of forming bimetallic core-shell metal nanoparticles including a core of a first metal material and a shell of a second metal material, the method including photochemically producing metallic nanoparticle cores of the first metal material, and forming a shell of the second metal material around the cores. The shell can be formed by adding shell-forming precursor materials to a solution or suspension of the cores and photochemically forming the shells around the cores, or by separately photochemically producing metallic nanoparticles of the second metal material and mixing the metallic nanoparticles of the second metal material and the metallic nanoparticle cores to cause the metallic nanoparticles of the second metal material to form a shell around the metallic nanoparticle cores.
专利号:US-10022366-B2 优先权日:2013-04-23 标 题:Extending and maintaining micropore viability of microneedle treated skin with lipid biosynthesis inhibitors for sustained drug delivery 发明人:STINCHCOMB AUDRA L; GHOSH PRIYANKA 权利人:STINCHCOMB AUDRA L; GHOSH PRIYANKA; UNIV MARYLAND; UNIV KENTUCKY RES FOUND 摘要:Microneedles and their use as a physical skin permeation enhancement technique facilitate drug delivery across the skin in therapeutically relevant concentrations. Micropores created in the skin by MNs reseal because of normal healing processes of the skin, thus limiting the duration of the drug delivery window. Pore lifetime enhancement strategies can increase effectiveness of MNs as a drug delivery mechanism by prolonging the delivery window. Fluvastatin (FLU) was used to enhance pore lifetime by inhibiting the synthesis of cholesterol, a major component of the stratum corneum lipids. The skin recovered within a 30-45-min time period following the removal of occlusion, and there was no significant irritation observed due to the treatment compared to the control sites. Thus, it can be concluded that localized skin treatment with FLU can be used to extend micropore lifetime and deliver drugs for up to 7 days across MN-treated skin.
